Now let’s check out the controllers performance in case we have a RAID 1 array.
In FAT32 file system we cannot actually name the leader. In Windows and Programs patterns Intel ICh6R is the best, while in all other patterns VIA VT8237 definitely looks better. SiS964 also demonstrated pretty good results, as it outperformed ICH5R and fell just a tiny bit behind the leaders.
File reading also doesn’t allow us to say who the winner is. The only thing we can state with all certainty is the fact that Intel’s duet is definitely the most attractive here.
During file copy within the same partition VIA VT8237 is the winner in ISO, MP3 and Install patterns. Also SiS964 looks pretty convincing. Intel controllers manage to keep pace with their competitors in all patterns except Windows.
The diagram built for file copying between the two different partitions allows stating evident victory VIA and SiS controllers over Intel’s products, which fall quite noticeably behind the leaders in most patterns. The performance difference becomes especially dramatic when we work with a limited number of large files.
